A:Answer There was a hack listed on another large online retailer’s site, haven’t tried it myself, but here is what they had.
UPDATE : Found a hack to disable the auto-shutoff. Press POWER button and VOLUME DOWN buttons on soundbar (not remote) simultaneously for 10 seconds.
This seems to have disabled the auto shutoff for 4 hours, based on my initial test. The soundbar went to standby after 4 hours. This may be tolerable, but I'll continue testing.”
